Abstract
1447660 Photographic development at elevated temperature FUJI PHOTO FILM CO Ltd 31 Dec 1973 [29 Dec 1972] 60200/73 Heading G2C A method of photographic development comprises developing in a developer solution at a temperature of at least 30‹C an imagewise exposed light-sensitive material having a spectrally sensitized silver halide emulsion layer containing at least one sensitizing dye having a halogen ion concentration-increasing effect (HICI effect) i.e. the dye when added to a specified test emulsion increases the halogen ion concentration. Fog normally obtained in high temperature development is reduced. Specified dyes are of the general formulae:- wherein R is sulphoalkyl, Z completes a benzoxazole, benzimidazole, benzothiazole or pyridine nucleus, R
